Below in conjunction with above-mentioned any embodiment one concrete example of offer:
In this example, terminal is by obtaining the characteristic parameter of base station, and carrying out this base station of comprehensive descision according to multiple parameters is No for pseudo-base station, relevant feature parameters (totally 6) be described below: (5 parameters in system message SI3, and the position of adjacent area Area identification (Location Area Identification, LAI).
1, minimum received signal level (RXLEV_ACCESS-MIN):
According to this value, mobile phone calculates cell selection parameters C1, so that C1 maximizes, pseudo-base station is traditionally arranged to be 0,0 The RSSI representing GSM can access for-110db.In the case of by, the minimum incoming level of some communication networks is set to- 104db can be accessed by, and have is set to-110db and can access.
Wherein, described C1 can use equation below to calculate:
C1=
RXLEV-RXLEV_ACCESS_MIN-MAX((MS_TXPWR_MAX_CCH-P),0)；
Described RXLEV is average reception level；
Described RXLEV_ACCESS_MIN is minimum incoming level；
Described MS_TXPWR_MAX_CCH is for controlling channel peak power；
Described P is the output level that communication terminal is maximum.
Described MAX (X1, X2) is for take maximum in X1 and X2.
Minimum received signal level is related to the calculating of cell selection parameters C1, and general minimum received signal level preferably connects It is bordering on the receiving sensitivity of terminal.This value is the least, and the access threshold of community is the lowest, also implies that and has more terminal Accessing, this also will cause cell business volume to transship, and certainly, normal Zone has voice, note, data, signaling etc.. But for pseudo-base station, in order to make more user access, the most just try every possible means to reduce and access threshold, thus minimum reception can be made Signal level arranges the lowest.
Rule of judgment, whether this minimum received signal level is 0, and being 0, there is a strong possibility is pseudo-base station；Certainly judgement is The no value meeting pseudo-base station feature can also be 0 to 5.
2, cell reselection offset (CELL_RESELECT_OFFSET):
This parameter is that terminal can consider emphatically when carry out cell reselection.Wherein, as Penalty time parameter (penalty_ Time, pt) value when being not equal to 31, C2=C1+CELL_RESELECT_OFFSET-TEMPORARY_OFFSET*H (PT- T), wherein, C1 is cell selection parameters, and C2 is cell reselection parameters, and TEMPORARY_OFFSET is cell reselection temporary offset Parameter, T is the timing time of enumerator.Described CELL_RESELECT_OFFSET is abbreviated as CRO；The meaning of H (PT-T) is H Being together decided on by PT and T, PT is Penalty time, if Penalty time deducts T and is less than 0, then and H=0；If Penalty time deducts T More than 0, then H=1.
If it will be seen that the value of CRO is too high, then the access priority of this community just promotes, terminal be easy to from Other Serving cell gravity treatment is to this community, and the most easily switches back into other community.So, this parameter of normal cell configuration is all Will not configure too high, because too high meeting causes this cell traffic load excessive, cause quality of service to deteriorate.Also it is unfavorable for this simultaneously The business of several communities, area is shared.The span of this cell reselection offset is 0-63.
Rule of judgment, whether this cell reselection offset is 63, and there is a strong possibility for pseudo-base station to be 63.(between 60-63 also Likely).
3, period position renewal intervalometer (TS3212):
T3212 is the intervalometer of periodic location update.If general existing network flow is relatively big, could be arranged to several little Time, mobile UNICOM's existing network is provided that 1 hour, if the setting of this value is too small, can increase the signaling burden of network.
When mobile phone sends after position updating request, pseudo-base station is so that mobile phone periodic location update as soon as possible and kicking out of Mobile phone, need to arrange this value is the least, and the T3212 that pseudo-base station is arranged is 1, time corresponding a length of 6 minutes, and this comes for existing network Say, as a consequence it is hardly possible to, according to network optimization principle, if within 6 minutes, just doing a location updating, it is likely that network is produced disaster Property impact.The most normally base station can not be set to 1.
The configuration of this intervalometer is the shortest, in the case of this subzone network capacity is certain, is more conducive to pseudo-base station timely Kick out of the user having received note then to suck and more the most do not receive the user of note to reach the business mesh of pseudo-base station , thus general pseudo-base station this value can be arranged the least, such as 1, that corresponding is 6min.If the too small meeting of this value causes community Signalling loads excessive, the power consumption of the terminal being simultaneously significantly increased.So normal base station cell will not be carried out such joining Put.Here we choose TS3212 namely time correspondence are less than or equal to 18min less than or equal to 3, and whether adjudicate this community is The community that pseudo-base station is formed.
Rule of judgment, whether this T3212 is 1, and there is a strong possibility for pseudo-base station to be 1；For example, it is also possible to think T3212 Value when being between 1 to 3, corresponding base station can also be pseudo-base station.
4, gprs_indicator_flag (GPRS sign):
GPRS sign is used for indicating whether this base station supports GPRS, owing to pseudo-base station does not typically the most support GPRS, institute System message with pseudo-base station broadcast does not typically comprise this parameter.
Rule of judgment: judge whether GPRS sign, if not existing, is the most probably pseudo-base station.
5、si2quater_indicator_flag；This parameter can be to indicate whether in the 3rd class system message SI3 The mark of two class system messages SI2, can be described as Equations of The Second Kind system message sign.
This Equations of The Second Kind system message sign parameter is the one in systematic parameter, when in the 3rd class system message SI2 Carry this parameter, and value is instruction when having Equations of The Second Kind system message, shows base station broadcast Equations of The Second Kind system to message, just Above-mentioned sign can be there is in the 3rd class system message that normal legitimate base station sends.Pseudo-base station is not owing to broadcasting SI2quater, is therefore generally not present this sign.
Rule of judgment: judge receive base station send system message only with whether there is this sign, if not existing, then Very possible is pseudo-base station.
6, the same frequency adjacent area (Location Area Identification) of different LAI:
Same frequency (ARFCN) community, Zhong Youzhe community, adjacent area, and this is different with this community LAI with the LAI of frequency point cell, Then local area has pseudo-base station feature.
